Designing a unique tool with a low threshold for error


We designed a facial and pupil scanning experience so customers could receive better fitting eyewear that they love, without ever having to step foot in a store.

The problem

Online eyewear shopping is difficult for customers and expensive for retailers. Customers have low confidence that what they buy will look good and feel comfortable on their face. Retailers spend a lot of money acquiring an online audience, only to run into exceptionally high return and re-make rates. Topology’s measurement and virtual try-on technology have the ability to address these problems, but only if they have high quality scans from customers. Our challenge was to have customers perform a foreign task that had a low threshold for error.

Quick, digestible instruction

Our user research found that—because this is not a common user experience—customers are happy to invest additional time on instruction to ensure that they are taking an accurate scan. We made a series of quick, swipeable videos to show users what to do, prior to taking their scan.

Accessible, intuitive scan

In addition to creating an experience most people are not familiar with, we also needed to account for that fact that we are asking people with vision impairments to remove their glasses to take a scan. We designed for this by showing big, bold graphics, playing audio instruction, and implementing haptic indicators.

Quick landmarking for ensured success

With the scan complete, landmarks need to be placed on the 3D object to ensure accurate measurements. This is another step that needs to be done accurately. We used iconography, quick videos, and text instruction to reduce the risk of error.
